What You’ll Need
True to its name, this soup comes together with just five core ingredients, letting the natural flavors shine through in the most comforting way. You’ll need one large head of green cabbage, cored and roughly chopped into hearty chunks—cabbage is the star here, so don’t be shy with it. You’ll also need about one and a half pounds of smoked sausage or kielbasa, sliced into thick rounds; the smoky, savory flavor of the sausage infuses the entire broth as it cooks.
For the liquid base, grab a carton of chicken or vegetable broth—about four to five cups—which keeps the soup light yet deeply flavorful. You’ll also need a large onion, chopped, and a few cloves of garlic, minced, to build that aromatic foundation. That’s it for the required five ingredients. An optional bay leaf and a pinch of black pepper add a little extra warmth, but since they’re optional, they don’t count toward your five.
How to Make It
Start by prepping your slow cooker—no need to grease it, as the sausage will release enough richness as it cooks to keep everything from sticking. Layer the chopped cabbage into the bottom of the slow cooker; it will seem like a massive mound, but cabbage wilts down dramatically as it cooks, so pile it in without worry. Scatter the chopped onion and minced garlic over the cabbage, then arrange the sliced sausage rounds on top, distributing them evenly so every bite gets a bit of that smoky goodness.
Pour the broth over everything, ensuring the liquid comes up about three-quarters of the way to cover the vegetables. If you’re using a bay leaf and a few grinds of black pepper, tuck them in now. Give everything a gentle stir just to combine, though you don’t need to overmix—the slow cooker will do all the work for you.
Cover the slow cooker with the lid and set it to cook on low for six to eight hours or on high for three to four hours. The low and slow approach is ideal here because it allows the cabbage to become meltingly tender while the sausage releases its smoky flavor into every corner of the broth. The longer it simmers, the more the flavors meld together into something truly special.
Once the cabbage is completely tender and the broth is deeply savory and fragrant, give the soup a good stir. Taste it and adjust with a little salt if needed—remember that the sausage is already salty, so add sparingly. Remove the bay leaf before serving if you used one.
Serving Suggestions and Tips
This soup is wonderfully hearty on its own, but it pairs beautifully with a thick slice of crusty bread, cornbread, or buttered crackers for dipping. A sprinkle of fresh parsley or dill on top adds a bright, fresh contrast to the rich, smoky broth.
One of the beauties of this recipe is how versatile it is. You can swap the smoked sausage for ham hocks, leftover ham, or even ground beef if that’s what you have on hand. Adding a can of diced tomatoes or a handful of chopped carrots turns this into an even more substantial meal, though that would take you beyond the five-ingredient promise—but it’s always an option for next time.
Leftovers keep beautifully in the refrigerator for up to four days and actually taste even better the next day as the flavors continue to deepen. The soup also freezes wonderfully for up to three months, making it perfect for batch cooking on a lazy weekend.
Enjoy this simple, wholesome soup that proves the best comfort food doesn’t need a long list of ingredients!
